Title: return newly-created operation object from shortcut methods

As discussed with richardwalsh in [Issue #93].

This commit will return the created `AFHTTPRequestOperation` from `[AFHTTPClient get/post/put/deletePath]` instead of `void`. So user can attach download progress block without creating `AFHTTPRequestOperation` directly, thus less line of code.

This is backward compatible with currently API.
